Abstract: A sealing strip, such as for fitting to the frame of a door opening in a motor vehicle body, comprises a longitudinally extending channel-shaped mounting portion incorporating a channel-shaped reinforcing carrier. The hollow tubular longitudinally extending sealing portion is attached to the outside of the mounting portion.
